That's right. With MMP, there are a number of different design variations. The big ones are the ratio between local representatives and the tier. The assembly members thought 70:30 was about right, with 25% on the tier about what you need. They wanted to return the legislature to pre-Mike Harris days, so it would have increased it from 103 to 129.
A number of other design decisions that the assembly members raised affect both proportionality and the values they wanted, including open and closed lists and the ballot structure. In Germany, in Saxony, you have an opportunity to rank your candidates in the local district. There's whether you want to have a threshold, and what the threshold would be. While the assembly members recognized that more parties might be better, they didn't want smaller obstreperous parties, shall we say, so they raised the floor at 5%.
